"This loss stings a lot; it's our toughest loss of the season," said LSU coach Paul Mainieri. "We have to rebound from this, get back to practice tomorrow and start building the players up again. We didn't really swing the bats well all weekend, and a lot of that is due to the arms Vanderbilt sent to the mound. But, there are no excuses - we just have to play better as we head into the final week of the regular season."

Vanderbilt rightfielder Mike Yastrzemski tied Sunday's game at 4-4 on a ninth-inning solo shot off of LSU closer Nick Goody.
